The epigenetic landscape in the cardiovascular complications of diabetes

Area of Science:

• Cardiovascular Science
• Epigenetics
• Diabetology

Background:

• Epigenetic modifications (e.g., DNA methylation, histone marks, non-coding RNAs) are increasingly recognized as key players in diabetes complications.
• These modifications can alter gene expression related to angiogenesis, oxidative stress, and inflammation, contributing to cardiovascular damage.
• Adverse epigenetic signals acquired during life can be heritable, potentially impacting cardiovascular health in subsequent generations.

Purpose of the Study:

• To review the current understanding of epigenetic modifications in the context of diabetes.
• To highlight the role of epigenetics in the development of cardiovascular complications in diabetic patients.
• To explore the potential of epigenetic insights for personalized therapeutic strategies.

Main Methods:

• This review synthesizes existing literature on epigenetics and diabetic cardiovascular disease.
• It examines evidence linking hyperglycemia and insulin resistance to specific epigenetic alterations.
• The review discusses the implications of these epigenetic changes for vascular and cardiac function.

Main Results:

• Hyperglycemia and insulin resistance induce epigenetic modifications that impair vascular and cardiac function long-term, even with glycemic control.
• Epigenetic alterations can disrupt transcriptional programs critical for cardiovascular homeostasis.
• Heritable epigenetic changes may contribute to early-onset cardiovascular phenotypes in offspring of diabetic individuals.

Conclusions:

• The "epigenetic landscape" in diabetes offers a comprehensive view of cardiovascular risk.
• Epigenetic modifications represent potential therapeutic targets for managing cardiovascular complications in diabetes.
• Personalized, epigenetic-based therapies hold promise for alleviating the burden of cardiovascular disease in diabetic populations.
